Patent EP-0288677-B1 (EP)
IPC: B32B7/02
Filed: 1988-02-22
Granted: 1992-08-19
Abstract: In the case of many machine elements, for example rolling bearings or rolling drives, which are subjected not only to rolling stress but at the same time also to sliding stress, this results in sliding wear in certain zones. In order to reduce this as far as possible, it is proposed to apply to the affected surfaces of such structural units a layer of a sliding bearing material which, however, according to the perception of the invention, has to be applied by a PVD method and has to be of a thickness of the order of magnitude of the surface roughness of the base element; known thicker sliding bearing coatings are not suitable. 
<??>Application of the invention in particular for gear wheels, rolling bearings, shafts, compressor screws and rolling pistons.

Abstract: A technique for rendering toxic metals (chromium, lead, cadmium and arsenic) contained in steel plant furnace dust innocuous and suitable for burial with minimal adverse environmental impact. Pelletized iron oxide containing dust is introduced into a rotary hearth furnace under a reducing atmosphere in excess of 600 DEG C. The higher iron oxides are reduced to FeO which in turn complexes with the toxic metals to form relatively benign products.

Abstract: The invention relates to a tailboard hinge having a hinge part (10) provided on the tailboard and possessing a hinge pin (15). Furthermore, a bearing lug (24) for the detachable reception of the hinge pin (15) is present on the loading surface. The hinge pin (15) possesses, moreover, a detent nose (17), so that the parts together form an unhinging safeguard dependent on the pivoting angle. Since known tailboard hinges are relatively complicated and the unhinging safeguard often operates precisely at critical pivoting angles, the object of the invention is to improve this. For this purpose, a specific angular orientation of the detent nose is provided, so that the unhinging of the tailboard is possible only within a specific angular sector. <IMAGE>

Abstract: A method for multicast communication wherein a multicast message is distributed to all the nodes (101-118) in a multicast range. If a multicast message has a multicast range which is larger than one link in the network then the message is forwarded along a unique set of pathways through the range. The unique set of pathways is called a multicast spanning tree and is unique to all nodes which can communicate directly by virtue of a list of known nodes. The network is divided into areas (130-133) each of which contains a group of directly communicating nodes (123, 125, 127). A group of nodes (121-127) designated as level two nodes facilitates communication between the nodes in different areas.

Abstract: In filtering particles such as soot from a flue gas a porous filter body of a particulate material bonded together in the body is employed. The material is a metal or metal-like material having a thermal conductivity in excess of 10 W/mK, and the porous filter body has a porosity of 50-90% and a maximum pore size of 10-40  mu m. The porous filter body also has a thermal conductivity in excess of 10 W/mK. In accordance with the method, the flue gas is conducted through the porous filter body so as to accumulate the particles in the porous filter body. The particles accumulated in the porous filter body are burned off, whereby heat is generated locally. The heat generated locally by the burning-off of the particles is conducted throughout the porous filter body so that the temperature rise generated by the burning-off heat is reduced. Consequently, the porous filter body is not exposed to fatal, thermal stresses. A particular application of the porous filter body of the flue gas filter means is in vehicles comprising combustion engines generating soot, such as in diesel engines.

Abstract: The efficiency of a blood plasmapheresis filter (12) is purposefully reduced at low input blood flow rates so as to prevent possibly excessive hematocrit which may make it difficult or impossible to handle the resulting blood cell concentrate (e.g., for infusion purposes) and/or which may cause accompanying red cell damage. Where filter (40) efficiency is a function of rpm of a spinning element such controlled reduction may be achieved by simply controlling spinner rpm as a function (e.g., linear over at least some range) of the input blood flow rate.
